I have a 07 boulevard c50 that I´m having a quitting issue. Most time when I start the bike if guess right up runs 30 seconds and acts just like u shut it off. This also happens one in a while when riding. Usually stopped at a light I begin to take off and the bike just quites. All I do is pull in the clutch lever and re fire the binge and go on. Any ideas what might be going on?
